8. Aqara E1 SRTS-A01
The Aqara Smart Radiator Thermostat E1 is compatible with a variety of ecosystems and voice assistants, including HomeKit, Alexa, Google, and IFTTT. It will also support the upcoming Matter standard.
External Temperature Measurements: The Aqara Smart Radiator Thermostat E1 can receive temperature readings directly from the connected Aqara Temperature and Humidity Sensor located in another corner of the room, even in HomeKit. This allows for more accurate temperature control for the entire room, enabling the thermostat to adjust the radiator based on the actual room temperature.
Energy Savings: When the Aqara Smart Radiator Thermostat E1 is connected to the Aqara Door and Window Sensor or the Aqara Motion Sensor, it will turn off the heating when it detects that a door or window is open or if no movement has been detected for a certain period. Additionally, schedules can be set for desired time periods such as day or night. It can automatically open or close the radiator valve, helping to reduce your energy consumption.
Geofencing and Support for Multiple Apartments: No more entering a cold apartment. When you set up geofencing, the Radiator Thermostat E1 will start heating the apartment before your arrival. If you own more than one apartment, you can set up automations for each of these apartments independently.
Support for Grouping of Different Devices: If there are multiple radiators in a room, they will all be synchronized in the most efficient way based on the actual room temperature.
Pro
- Reading very good
- Very easy to install
